Just to clarify what I wanted to say:
So-called Dual Intent LMIA refers to http://www.esdc.gc.ca/eng/jobs/foreign_workers/higher_skilled/permanent/index.shtml Hiring Skilled Workers and Supporting their Permanent Residence, LMIA Application Form (EMP5593).
In the form itself, the one should tick box 1 or box 2, under "Purpose of application".
"permanent resident visa application (this means you will hire the foreign national only after their immigration application is processed and the
permanent resident visa is issued). This option does not have a processing fee.
OR
work permit application and permanent resident visa application (this means you will hire the foreign national as a temporary foreign worker before or
while their permanent residence application being processed). This option requires paying a processing fee."
The second box is dual intent. As you can see from the checklist on the link above, there is no transition plan. Why? Because the employer is already doing one activity to transit to the Canadian workforce by supporting PR application.
If the employer wants to employ a foreign worker temporarily, the one should submit http://www.esdc.gc.ca/eng/jobs/foreign_workers/high_low_wage/high_wage/index.shtml LMIA Application Form (EMP5602).
In that case, the employer needs to submit transition plan as well.
At the bottom line, BOTH LMIAs will give you 600 extra points for EE, and can be used to help obtain PR.
